enum OpCode

Operator codes for the pseudo-assembler.

Enumerator:

NOP	NOP instruction; does nothing.
LDA	LDA instruction; loads something into register A.
LDB	LDB instruction; loads something into register B.
STA	STA instruction; stores the content of register A in a virtual address.
STB	STB instruction; stores the content of register B in a virtual address.
INP	INP instruction; ask for input and store the input in register A.
OUT	OUT instruction; output the value in register A.
ADD	ADD instruction; store the value in register A + the value in register B in register A.
SUB	SUB instruction; store the value in register A - the value in register B in register A.
MUL	MUL instruction; store the value in register A * the value in register B in register A.
DIV	DIV instruction; store the value in register A / the value in register B in register A.
JMP	JMP instruction; unconditionally jump to some line (or address).
JSP	JSP instruction; jump to some line (or address) when the value in register A is strictly positive.
JSN	JSN instruction; jump to some line (or address) when the value in register A is strictly negative.
JIZ	JIZ instruction; jump to some line (or address) when the value in register A is equal to 0.
JOF	JOF instruction; jump to some line (or address) when an overflow occured.
JSB	JSB instruction; unconditionally enter some subroutine.
RTS	RTS instruction; return back from the subroutine.
HLT	HLT instruction; stop the program.
